“…Detailed studies to unravel the role of singlet oxygen species in inactivation of fungi have been carried out by Hori and co‐workers (Hashizume et al., , , ; Iseki et al., ; Ishikawa et al., ). Through a comprehensive set of experiments, they reported that ROS, particularly O( 3 P j ), from an atmospheric pressure oxygen plasma potentially inactivates fungi.…”

Cold plasma treatment is a promising intervention in food processing to boost product safety and extend the shelf‐life. The activated chemical species of cold plasma can act rapidly against micro‐organisms at ambient temperatures without leaving any known chemical residues. This review presents an overview of the action of cold plasma against molds and mycotoxins, the underlying mechanisms, and applications for ensuring food safety and quality. The cold plasma species act on multiple sites of a fungal cell resulting in loss of function and structure, and ultimately cell death. Likewise, the species cause chemical breakdown of mycotoxins through various pathways resulting in degradation products that are known to be less toxic. We argue that the preliminary reports from cold plasma research point at good potential of plasma for shelf‐life extension and quality retention of foods. Some of the notable food sectors which could benefit from antimycotic and antimycotoxin efficacy of cold plasma include, the fresh produce, food grains, nuts, spices, herbs, dried meat and fish industries.

“…DI water (18.2 MΩ•cm at 25 • C) was produced by a Direct-Q 3UV (Millipore, Tokyo, Japan) system. To compare the performance of the developed AALCA to commonly used plasma sources, DI water was treated using AALCA, a commercially available NEAPPJ (PN-110/120TPG, NU Global Co., Ltd., Nagoya, Japan) [40], and a high-density nonequilibrium atmospheric pressure radical source (NEAPRS, Tough Plasma FPA10, Fuji MFG Co., Ltd., Tokyo, Japan) [4,31,41].…”

In this work, we developed a portable device with low production and operation costs for generating an ambient air low-current arc (AALCA) that is transferred to the surface of a treated liquid. It was possible to generate a stable discharge, irrespective of the conductivity of the treated liquid, as a sequence of corona, repeating spark, and low-current arc discharges. The estimated concentration of reactive oxygen and nitrogen species (RONS) in plasma-treated water (PTW) produced using AALCA treatment was two orders of magnitude higher than that of PTW produced using conventional He nonequilibrium atmospheric pressure plasma jets or dielectric barrier discharges. The strong bactericidal effect of the treatment using AALCA and the water treated using AALCA was confirmed by survival tests of Escherichia coli. Further, the possibility of treating a continuous flow of liquid using AALCA was demonstrated.

Plasma medical science is a novel interdisciplinary field that combines studies on plasma science and medical science, with the anticipation that understanding the scientific principles governing plasma medical science will lead to innovations in the field. Non-thermal atmospheric pressure plasma has been used for medical treatments, such as for cancer, blood coagulation, and wound healing. The interactions that occur between plasma and cells/tissues have been analyzed extensively. Direct and indirect treatment of cells with plasma has broadened the applications of non-thermal atmospheric pressure plasma in medicine. Examples of indirect treatment include plasma-assisted immune-therapy and plasma-activated medium. Controlling intracellular redox balance may be key in plasma cancer treatment. Animal studies are required to test the effectiveness and safety of these treatments for future clinical applications.Keywords Plasma medical science Á Plasma cancer therapy Á Plasma-activated medium (PAM) Á Reactive oxygen species (ROS) Abbreviations ALKAnaplastic lymphoma kinase AMD Age-related macular degeneration APF Aminophenyl Fluorescein CNV
